    Subject: Re: Attaching "uninsulated ring terminals" to
    4 awg wire... Greetings, I wasn't describing stacking processes. I was suggesting that the process of "wedging" might be replaced by compressing the components together with a "whack-n-bash" tool. It would avoid the - find the wire - find the sharpening tool - strip - sharpen - drive - nip - process of wedging. Seems quicker and at least as repeatable as "wedging", if it doesn't introduce additional issues I'm not considering. Just wondering out loud. Thanks, Raymond Julian Kettle River, MN.

Yes, anything you do to minimize voids in the wire grip before soldering is a good thing to do. If copper 'wedging' is unattractive then reducing the cross section of the terminal barrel is another option. The wire for wedges is pretty easy. Most hardware stores will sell 14/2+ground house wire by the foot. Buy one foot and you'll have 3 feet of wedge material. It's pvc insulation and comes off easy with a pocket knife. I get sharp ends by cutting the pieces with the tool as close to parallel with the wire as it will permit. Pushing the wedges in can be done with the same pair of wire cutters. The last one will need to be driven . . . I use the wire cutter for that too. Bob . . .

    wire... Hi guys, I haven't read all the posts on this thread ... please forgive me if I'm covering old ground. Not everyone's cup-o-tea, but you can make dies like this too. Just cut two bits of the same steel bar to length, hold them together in a vice, drill a big hole at the join from the top in one direction and a small hole from the side. Smooth the end of a rod or pin punch and there you have it, a decent die you can hold in the vice that will retain the shape of your terminal as you crimp away the void, prior to solder and heatshrink. Cheers, Stu
